The cover ring contacts the top of the ball valve to prevent the paint from being sprayed into the inside of the ball valve later, and the two clamping rods clamp the inner wall of the ball valve, and then the worker starts the servo motor and the paint spray gun, and the paint spray gun sprays paint around the reversed ball valve; after the rotating gear rotates around the ball valve, the paint spray gun moves downward a certain distance, and so on, so that the paint spray gun sprays paint on the ball valve more comprehensively, thereby better anti-corrosion treatment of the ball valve.

Description

[0001] The invention relates to the technical field of ball valve painting, and in particular to an anti-corrosion treatment device for a ball valve. Background Art

[0002] In the production process of ball valves, spraying process is an indispensable link. The painting steps are generally primer painting, mid-coat painting and topcoat painting. Spraying paint on the ball valve can effectively ensure the corrosion resistance of the ball valve surface.

[0003] At present, when a ball valve is sprayed with paint, it is usually done with a spray gun. However, the shape of the ball valve is relatively special. During the spraying process, the angle of the spray gun is relatively fixed, and the top and bottom of the ball valve are not easily sprayed sufficiently, resulting in insufficient spraying of the ball valve, poor painting effect, and thus poor anti-corrosion effect of the ball valve. In addition, during the painting process, the paint can easily enter the inside of the ball valve through the opening at the top of the ball valve.

[0014] The beneficial effects of the present invention are as follows: 1. The cover ring contacts the top of the ball valve to prevent the subsequent spraying of paint into the inside of the ball valve. The fixed pressure rod penetrates into the inside of the ball valve, and the fixed pressure rod squeezes the two clamping rods to move away from each other, so that the two clamping rods clamp the inner wall of the ball valve. Then the worker starts the servo motor and the paint spray gun, thereby driving the paint spray gun to rotate forward around the ball valve. The forward rotation of the central gear drives the pinion gear, the transmission rod and the transmission gear to reverse, so that the ball valve is reversed, and the paint spray gun sprays paint around the reversed ball valve; when the rotating gear rotates forward, the paint spray gun rotates forward. When the rotating gear is rotated around the ball valve, the rotating gear will be disengaged from the fixed arc-shaped rack. After the rotating gear rotates around the ball valve in the forward direction, the rotating gear will be meshed with the fixed arc-shaped rack again. The fixed arc-shaped rack drives the rotating gear to rotate at a certain angle, so that the lifting seat moves downward along the fixed guide rod for a certain distance. The lifting seat drives the swing rod, the connecting frame and the paint spray gun to move downward for a certain distance, and then the paint spray gun continues to rotate around the ball valve in the forward direction, and so on and so forth, so that the paint spray gun can paint the ball valve more comprehensively, thereby better performing anti-corrosion treatment on the ball valve.

[0015] 2. At first, the nozzle of the paint spray gun is tilted downward, so that the paint spray gun can spray to the top of the ball valve. When the lifting seat moves downward, the paint spray gun swings to a horizontal state, and then the lifting seat continues to move downward, and the lifting seat drives the swing rod, the sliding rod, the connecting frame and the paint spray gun to move downward. The paint spray gun remains in a horizontal state and sprays paint on the side of the ball valve. Then the lifting seat drives the sliding rod to move to the lower inclined part of the guide groove on the fixed arc guide plate, and the lifting seat drives the swing rod away from the end of the ball valve to swing downward, and the swing rod drives the connecting frame and the paint spray gun to swing, so that the nozzle of the paint spray gun tilts upward, so that the paint spray gun sprays paint on the bottom of the ball valve, further improving the comprehensiveness of the ball valve painting and having a better anti-corrosion effect.

[0016] 3. When the lifting plate rotates forward, it will drive the fixed lifting rod to rotate forward. The corrugated surface at the bottom of the fixed corrugated rod will squeeze the fixed lifting rod and the lifting plate to move upward. The fixed lifting rod continues to rotate forward, and the corrugated surface at the bottom of the fixed corrugated rod no longer squeezes the fixed lifting rod. The reset spring resets and drives the lifting plate and the fixed lifting rod to move downward, and so on, so that the lifting plate moves back and forth up and down. The up and down reciprocating movement of the lifting plate drives the rotating screw, lifting seat, swing rod, connecting frame and paint spray gun to move back and forth up and down, thereby increasing the painting range of the paint spray gun and further improving the comprehensiveness of the ball valve painting.

A fixed arc-shaped rack 77 is welded to the bottom of the box body 1, and the rotating gear 76 meshes with the fixed arc-shaped rack 77.

[0035] The swing mechanism includes a fixed arc guide plate 81, a fixed curved rod 82, a compression spring 83, a swing rod 84, a sliding rod 85, a connecting frame 86 and a paint spray gun 87. The top of the lifting plate 72 is welded with a fixed arc guide plate 81, and a guide groove is opened on the fixed arc guide plate 81. The guide groove of the fixed arc guide plate 81 is composed of an upper inclined portion, a straight portion and a lower inclined portion. The lifting seat 75 is fixedly connected with a fixed curved rod 82, and the lifting seat 75 is rotatably connected with a swing rod 84. The swing rod 84 is connected to the fixed curved rod 82. The rod 82 is slidably connected, and two compression springs 83 are connected between the swing rod 84 and the lifting seat 75 through a hook. The two compression springs 83 are both sleeved on the fixed curved rod 82. The swing rod 84 has two straight grooves. A sliding rod 85 is placed between the two straight grooves on the swing rod 84. The sliding rod 85 is located in the guide groove of the fixed arc guide plate 81. A connecting frame 86 is fixedly connected to one side of the swing rod 84, and a paint spray gun 87 is fixedly connected to the connecting frame 86. The paint spray gun 87 is used to spray paint on the surface of the ball valve.

[0036] The clamping mechanism includes a clamping rod 121 and an extrusion spring 122. Two clamping rods 121 are slidably connected to the upper part of the fixed base frame 65. The two clamping rods 121 are symmetrically arranged. The two clamping rods 121 are used to clamp the inner wall of the ball valve. The extrusion spring 122 is connected between the two clamping rods 121 and the fixed base frame 65 through a hook.

[0037] The two clamping rods 121 are provided with inclined surfaces on the sides close to each other.

[0038] At first, the worker introduces paint into the connecting pipe 9, and the paint enters the space between the fixed hollow frame 10 and the annular closing rod 11, and then the paint enters the hose 112 through the annular closing rod 11, and the hose 112 transports the paint to the paint spray gun 87. When the ball valve needs to be painted, the worker pulls up the hand lever 62, and the hand lever 62 drives the rotating groove rod 61, the cover ring 611 and the fixed pressure rod 63 to move upward, and then places the ball valve to be painted on the rotating bottom ring 64, and then releases the hand lever 62. The hand lever 62 moves downward under the action of gravity and drives the rotating groove rod 61, the cover ring 611 and the fixed pressure rod 63 to move downward, and the cover ring 611 is connected to the top of the ball valve. To prevent the subsequent paint from being sprayed into the ball valve, the fixed pressure rod 63 will penetrate into the ball valve, and the bottom end of the fixed pressure rod 63 will contact the inclined surfaces on the two clamping rods 121. The fixed pressure rod 63 squeezes the two clamping rods 121 to move away from each other, so that the two clamping rods 121 contact the inner wall of the ball valve, thereby making the two clamping rods 121 clamp the inner wall of the ball valve. Then the worker starts the servo motor 3 and the paint spray gun 87. The servo motor 3 drives the power gear 4 to rotate forward through the output shaft, and the power gear 4 drives the transmission gear 42 to reverse, and the transmission gear 42 drives the rotating ring 41 to reverse, and the rotating ring 41 drives the rotating groove rod 61, the fixed pressure rod 63 and the center gear 67 to rotate forward, and the rotating The groove rod 61 drives the vertical rod 71, the lifting plate 72, the fixed guide rod 73, the rotating screw 74, the lifting seat 75, the rotating gear 76, the fixed arc guide plate 81, the fixed bending rod 82, the compression spring 83, the swing rod 84, the sliding rod 85, the connecting frame 86 and the paint spray gun 87 to rotate forward, so that the paint spray gun 87 rotates forward around the ball valve, and the forward rotation of the central gear 67 drives the pinion 69, the transmission rod 68 and the transmission gear 610 to reverse, and the transmission gear 610 drives the fixed inner ring 66, the fixed base frame 65 and the clamping rod 121 to reverse, and the clamping rod 121 drives the ball valve to reverse, and the paint spray gun 87 sprays paint around the reversed ball valve; when the rotating gear 76 rotates forward, the rotating gear 76 will disengage from the fixed arc-shaped rack 77. After the rotating gear 76 rotates around the ball valve in the forward direction, the rotating gear 76 meshes with the fixed arc-shaped rack 77 again. The fixed arc-shaped rack 77 drives the rotating gear 76 to rotate a certain angle. The rotating gear 76 drives the rotating screw 74 to rotate a certain angle. The rotating screw 74 drives the lifting seat 75 to move a certain distance downward along the fixed guide rod 73. The lifting seat 75 drives the swing rod 84, the connecting frame 86 and the paint spray gun 87 to move a certain distance downward. Then the paint spray gun 87 continues to rotate around the ball valve in the forward direction, and this reciprocating process allows the paint spray gun 87 to paint the ball valve more comprehensively, thereby better performing anti-corrosion treatment on the ball valve.

[0039] At first, the straight groove on the swing rod 84 and the upper inclined portion of the guide groove on the fixed arc guide plate 81 jointly limit the sliding rod 85, the compression spring 83 located at the top is stretched, and the compression spring 83 located at the bottom is compressed, the swing rod 84 and the connecting frame 86 are in an inclined state, and the nozzle of the paint spray gun 87 is in a downwardly inclined state, so that the paint spray gun 87 can spray to the top of the ball valve. When the lifting seat 75 moves downward, the two compression springs 83 will recover, so that the swing rod 84 and the connecting frame 86 will swing to a horizontal state, and the connecting frame 86 will drive the paint spray gun 87 to swing to a horizontal state, and then the lifting seat 75 will continue to move downward, and the lifting seat 75 will drive the swing rod 84, the sliding rod 85, the connecting frame 86 and the paint spray gun 87 to move downward, and the sliding rod 85 will be in the straight groove on the swing rod 84 The lifting seat 75 moves, and then the lifting seat 75 continues to move downward, thereby driving the sliding rod 85 to move to the straight part of the guide groove on the fixed arc guide plate 81, and the paint spray gun 87 remains in a horizontal state and sprays paint on the side of the ball valve. Then the lifting seat 75 drives the sliding rod 85 to move to the lower inclined part of the guide groove on the fixed arc guide plate 81, and the lower inclined part of the guide groove on the fixed arc guide plate 81 blocks the sliding rod 85, and the sliding rod 85 stops moving downward, and the lifting seat 75 continues to move downward, and the lifting seat 75 drives the swing rod 84 to swing downward away from the end of the ball valve, and the swing rod 84 drives the connecting frame 86 and the paint spray gun 87 to swing, so that the nozzle of the paint spray gun 87 is tilted upward, so that the paint spray gun 87 sprays paint on the bottom of the ball valve, further improving the comprehensiveness of the ball valve painting and having a better anti-corrosion effect.

[0040] When the ball valve is finished painting, the worker closes the paint spray gun 87, then adjusts the servo motor 3 to reverse, so that the lifting seat 75 intermittently moves upward and resets, and then pulls up the hand lever 62 again, so that the fixed pressure rod 63 is disengaged from the inside of the ball valve, and the fixed pressure rod 63 is disengaged from the two clamping rods 121. The extrusion spring 122 is reset to drive the clamping rod 121 to reset, and the clamping rod 121 no longer clamps the inner wall of the ball valve. Finally, the worker takes out the painted ball valve.

[0041] Embodiment 2: Based on embodiment 1, Figure 7 and Figure 8 As shown, it also includes a fixed corrugated rod 13, a fixed lifting rod 14 and a reset spring 15.

The lower part of the fixed corrugated rod 13 is provided with a corrugated surface. The fixed lifting rod 14 is fixedly connected to the top of the lifting plate 72. The upper end of the fixed lifting rod 14 contacts the corrugated surface of the lower part of the fixed corrugated rod 13. The corrugated surface of the lower part of the fixed corrugated rod 13 is used to squeeze the fixed lifting rod 14 so that the fixed lifting rod 14 moves back and forth up and down. A reset spring 15 is connected between the lifting plate 72 and the rotating slot rod 61, and the reset spring 15 is sleeved on the vertical rod 71.

[0042] When the lifting plate 72 rotates forward, it will drive the fixed lifting rod 14 to rotate forward, and the corrugated surface at the bottom of the fixed corrugated rod 13 will squeeze the fixed lifting rod 14 and the lifting plate 72 to move upward. The fixed lifting rod 14 continues to rotate forward, and the corrugated surface at the bottom of the fixed corrugated rod 13 no longer squeezes the fixed lifting rod 14. The reset spring 15 resets and drives the lifting plate 72 and the fixed lifting rod 14 to move downward, and so on and so forth, so that the lifting plate 72 moves back and forth up and down. The up and down reciprocating movement of the lifting plate 72 drives the rotating screw 74, the lifting seat 75, the swing rod 84, the connecting frame 86 and the paint spray gun 87 to move back and forth up and down, thereby increasing the paint spraying range of the paint spray gun 87 and further improving the comprehensiveness of the ball valve paint spraying.

[0043] Embodiment 3: Based on embodiment 2, Figure 3 and Fig. 9 As shown, it also includes a limit ring 16 and a deformation spring 17. The lower part of the rotating groove rod 61 is rotatably connected to the limit ring 16, and the deformation spring 17 is connected between the limit ring 16 and the cover ring 611 through a hook.

[0044] It also includes a collecting frame 18 and a drain pipe 19. The collecting frame 18 is fixedly connected to the lower part of the central base 5. The collecting frame 18 is used to collect excess paint. The bottom of the collecting frame 18 is fixedly connected to the drain pipe 19. The drain pipe 19 is connected to the collecting frame 18 and passes through the bottom of the box body 1.

[0045] Initially, the ball valve squeezes the cover ring 611 to move upward, and the deformable spring 17 is compressed. The deformable spring 17 can apply pressure to the cover ring 611, so that the cover ring 611 covers the opening at the top of the ball valve more stably.

[0046] During the painting process, excess paint on the surface of the ball valve will flow into the collection frame 18, and the paint in the collection frame 18 will be discharged through the drain pipe 19, so that the excess paint can be collected conveniently.
